If Delta airlines can afford only one major system upgrade at this time, describe how one of the following types of systems could contribute to the value of Delta and influence the business strategychoose either: computer-aided design/computer-aided manufacturing (CAD/CAM), supply chain management (SCM) systems, customer relationship management (CRM) systems, or enterprise resource planning (ERP) systems. CAD/CAM systems enable businesses to design and manufacture unique products to differentiate themselves in the marketplace. SCM systems can improve efficiency and reduce costs if a business has a large number of suppliers and products. CRM systems enable businesses to better manage customer information to develop deep relationships with customers. ERP systems help to manage resources (e.g., finance, inventory, human resources) to improve the efficiency of business operations. Even though your business may use many types of systems, focus on one (CAD/CAM, SCM, CRM, or ERP) that is most important for your business strategy.
